Latest Patents
One of his latest patents is a method and apparatus for saving printer memory. This invention involves a page printer that utilizes alternative internal representations for print data across multiple lateral strips that compose a page. The page description language input is transformed into an intermediate display list format, which is organized into display commands linked to each strip. If the display list representation fills the allocated memory during input, one or more strips are converted from display list format to raster format and compressed using a lossless compression algorithm. Should the storage of compressed strips exceed available memory, the raster data undergoes further compression through a lossy compression algorithm. Additional display list commands are rasterized by decompressing the compressed strips, processing the new commands, and recompressing the data as necessary. If the display list does not overflow memory during input, the complete strips are rasterized and compressed sequentially. The rasterizing time is recorded, and if memory overflows at any point, the rasterizing times for the remaining strips are determined without storing the raster output. A decision is then made for each strip regarding whether to rasterize it to the print engine on the fly, precompute and store it as lossless compressed raster data, or revert to a lossy-compressed precomputed version.
